It is trivial with RODBC (I know that is not what you asked, but it is the
solution we found first).
For RMySQL, note first that the MySQL configuration file is consulted, so
the default host is specified in the client section, which is like
[client]
port=3306
[mysql]
Hello,
I'm new to R. If I have a set of 10 points (X(i), Y(i)), is there an elegant
way to build a function y=f(x) that would be build out of the consecutive
segments of X(j),Y(j) points (with X(j) sorted)?
Thank you very much

First, you will likely have to use Ctrl-Alt-Delete - Task Manager - to
kill the Excel processes.
you could also try
wb[[Saved]]-TRUE # trick Excel to think that the workbook is
saved
x$Quit() # close Excel
rm(list=ls()) # remove all objects attached to environment

Hello all,
I'm trying to modify a single column of a data frame to remove randomly half of
the values. I want to do it within a function, but can not assign the modified
column back into the data frame. It was easy and successful without a function,
so I suspect the problem is the call of the
Hey Giovanni,
thanks a lot for the help. I tried out combining the two functions
dlmModARMA and dlmMLE and it works. The only problem I have right now is
this. When I pass on the information about the starting parameters (param)
in the dlmMLE function I can only input one parameter vector.
This has been reported several times. I posted a workaround earlier this
week:
https://stat.ethz.ch/pipermail/r-help/2007-December/148290.html
so your searching of the archives was not very thorough!
Another workaround is to use rterm instead of Rgui.

For the record, the problem with truncated fields below was solved by
increasing the Max LongVarChar variable in the data source settings page 1 from
8190 to 32760. So it was a psqlODBC problem not an RODBC problem. The command
nchar(Grids$Grids) helped me see how large the fields actually were
You need to read about scope.
Try using return() from within your function to return the modified
data frame to the caller.
Best wishes,

I am using lrm in Design package for a project using logit analysis.
I think lrm is very useful for providing information about the number of
missing values due to the inclusion of each variable.
My first questions is: How to explore those observations that are
automatically deleted from the lrm?

If I want to do:
(1) if M[i,j]=0.3, M[i,j]=1
(2) if M[i,j]=-0.3, M[i,j]=-1
(3) Otherwise, M[i,j]=0
Try:
(M = 0.3) - (M = 0.3)

Indeed, I noticed the host argument but the server demands an username and a
password for the machine first, and only after that for the MySQL server.
Those were the arguments I was looking for.
I will study the RODBC package then, if it solves the problem.
Thank you very much,

One alternative would be to use ggplot2 with a polar coordinate system:

qplot(mpg, wt, data=mtcars) + coord_polar()
qplot(mpg, wt, data=mtcars, ylim=c(3,4)) + coord_polar()
etc. You can see more examples of polar coordinates at
